He aha te Antenna Rhombic?
Ko te pūihi porowhita he pūihi waea ahunga e hangaia ana e ngā huānga kawe hiko e whā kua whakaritea ki te hanganga taimana. Ka taea te tiro hei pūihi V e rua e hono ana mai i te pito ki te pito, me te pito koi kotahi e whakamahia ana hei pūwāhi whāngai, ā, ko te pito ke atu e hono ana ki te ātete whakamutunga.
He rerekē tēnei i te pūihi porowhita e mutu tika ana, ā, ko te mahi matua he pūihi ngaru haere. Ka haere te iahiko RF mai i te pūwāhi whāngai i ngā wāhanga waea e whā ki te kawenga whakamutu. Ka honoa ngā mara hikohiko e puta mai ana i ēnei wāhanga hei hanga i tētahi hihi kukū i te tuaka matua o te porowhita.
I rongonui ngā pūihi Rhombic mō te whakawhitiwhiti HF tawhiti-roa nā te mea ka taea e rātou te whakarato i te whānuitanga o te auau, te whai hua whakamua me ngā āhuatanga ahunga pumau. Heoi, nā te rahi tinana nui, he pai ake mō ngā whakaurunga pumau i ngā papa whakawhitiwhiti kiato.
Hanganga Taketake
Ko te pūihi porowhita tuku iho he mea hanga ki ngā waea e whā, he rite te roa, e iri ana i runga ake i te whenua. Ka hangaia e ēnei waea he porowhita whakapae me ngā koki koi e rua me ngā koki pūngoi e rua.
Ka whāngaihia te pūihi i tētahi pito, ko te pito kē ka honoa ki tētahi ātete whakamutu kore-whakaoho. Ka tīpakohia tēnei ātete kia tata ki te ātete āhuatanga o te hanganga pūihi, kia mimiti ai hoki te kaha ngaru haere e toe ana.
Ko ngā tawhā hoahoa matua ko:
- Te roa o ia wāhanga waea
- Koki koi, koki tihi rānei o te rhombus
- Teitei o te tāutanga i runga ake i te whenua
- Ātete whāngai-ira
- Te whakamutu i te ātete
- Diameter o te kaiārahi
- Te whānuitanga auau ūnga me te ara horapa
Ehara te koki tino pai i te uara pumau whānui. E whakawhirinaki ana ki te roa hiko o ia taha me te teitei me te ahunga azimuth e hiahiatia ana o te hihi matua.

He pēhea te mahi a te pūihi Rhombic?
He rite te mahi a ia taha o te porowhita ki te pūwhakamahana waea roa. I te horapa o te iahiko i runga i ngā kaiārahi hiko, ka puta he wāhanga irahiko aronga i ia wāhanga waea.
Ina tīpakohia tika ngā rahi me ngā koki o te pūihi, ka whakakaha ngā mara e whitihia ana e ngā taha e whā tetahi ki tetahi i te ahunga whakamua. I ētahi atu ahunga, ka whakakorea ētahi wāhanga o te mara. Ko te hua whakakotahi he hihi matua whaiti i te taha roa o te porowhita.
He mahi nui tā te ātete whakamutunga. Mā te mimiti i te kaha e tae atu ana ki te pito tawhiti, ka whakaitihia te whakaata o te iahiko, ā, ka ārai i te ngaru tū kaha kei puta ki ngā kaiārahi. Mā tēnei ka āwhina i te pūihi ki te pupuri i te aukati me ngā āhuatanga irahiko pumau puta noa i te awhe auau whānui.
Ko te taupatupatu ko te whai huatanga. Ka hurihia tetahi wāhanga o te mana tuku hei wera i roto i te ātete whakamutunga, kaua e tukuna ki te irahiko. Nō reira, me whai taurite te hoahoa pūihi i waenga i te aronga, te whānui o te hononga, te pumau o te aukati me te whai huatanga o te irahiko.
Awhe Auau me te Rahi Hiko
Ko ngā pūihi porowhita rahi-katoa tuku iho te mea tino hono ki te whakawhitiwhiti HF. I ēnei auau, he maha ngā roangaru o ngā taha pūihi, e āhei ai te hanganga ki te whakaputa i te ahunga nui.
Kāore te pūihi porowhita e tautuhia ana e te awhe auau pumau kotahi. Ka taea te whakatau i ōna inenga mō ngā auau rerekē, engari ka tino nui te hanganga i ngā auau iti ake, ā, me kaha ake ngā manawanui ā-pūkaha i ngā auau teitei ake.
Ka taea hoki te whakamahi i ngā hanganga porowhita-rhombic me ngā hanganga porowhita-rhombic kiato i ngā auau VHF, UHF, ngaruiti rānei. Heoi, ka rerekē pea ngā āhuatanga whāngai, pōraritanga me te irahiko o ēnei hoahoa tauine mai i tētahi pūihi porowhita HF tuku iho.

Ngā Antenna Rhombic kua Whakamutua me te Kāore i Whakamutua
Ko te tikanga, ka puta he tauira irahiko kotahi-angihanga i tētahi pūihi porowhita kua mutu. Ko te nuinga o ngā irahiko whai hua ka ahu mai i te pūwāhi whāngai ki te pito whakamutunga.
Ki te tangohia te ātete whakamutunga, ka whakaatahia te iahiko mai i te pito tuwhera. Kātahi ka whakawhanakehia e te pūihi he wāhanga ngaru tū kaha ake, ā, ka taea te whakaputa i tētahi tauira ahunga-rua, me te irahiko nui i ngā ahunga e rua e rerekē ana.
Ka taea e te whirihoranga kāore i mutu te karo i te ngaronga hiko i roto i te ātete whakamutu, engari ko tōna aukati whakauru me te tauira irahiko he rerekē ake i te auau. Tērā pea ka whakaatu i te ōwehenga o mua-ki-muri he ngoikore ake, me te whanonga whānui kāore i te tino matapaetia.
Tauira Irahiko me te Pōrairatanga
Ko te tauira hihi o te pūihi porowhita kua mutu ka tohuhia e te pūihi matua whakamua me ngā pūihi taha maha. Ko te ahunga hihi me te whānui hihi tika ka whakawhirinaki ki te roa taha, te koki porowhita, te teitei tāutanga, te auau whakahaere me ngā āhuatanga whenua.
Mā te whakanui ake i te roa o te hiko ka taea te whakapai ake i te aronga, engari ka taea hoki te whakaputa i ētahi atu porowhita taha. Tērā pea ka tukuna e ēnei porowhita kāore e hiahiatia te pūngao ki ngā ahunga kāore i te hiahiatia, ā, ka whakaiti i te painga mahi o te hihi matua.
Ko te pūihi porowhita whakapae kua tāutahia, he porowhita whakapae te nuinga i te ahunga matua o te hihi. Heoi, tera pea kei roto i te tauira toru-ahu katoa ngā wāhanga porowhita poutū, inā koa i ngā taha taha me ngā ahunga e matara atu ana i te tuaka matua.

Te Whāngai me te Taurite Āraitanga
Ko te pūihi porowhita he hanganga taurite me te aukati tāuru teitei. He maha ngā wā ka whāngaihia mā te whakamahi i tētahi raina tuku taurite, mā tētahi whakawhiti aukati me te pere rānei e tika ana.
Ina whakamahia te taura coaxial, me āta hoahoa te whakawhiti i waenga i te raina whāngai kore taurite me te pūihi taurite. Mā te kore taurite e ranea ka piki ake te mana whakaata, ka puta te iahiko aratau-noa, ka whakapohehe i te tauira irahiko e hiahiatia ana.
